Even though Steve Jobs never talked about changing the face of search with Siri, its natural language interface.

But doing so would certainly be a riveting Hollywood screenplay in which Jobs, the uber-innovative, uber-inventive CEO, ultimately gets revenge on a corporate rival he views as a “copy cat.”

In this fictional script, that rival would be Eric Schmidt, one of the top executives at search giant Google. It’s Google, after all, that’s breathing down Apple’s neck with its rapidly expanding Android phone platform – a platform that, according to Jobs and his lawyers, mimics Apple’s breakthrough iPhone technology.

Putting this Oscar dream aside, there’s intensifying competition heating up between Apple and Google, even though Jobs is –sadly – no longer on the scene.

Indeed, even though Google has had voice-enabled search for some time on iOS and Android devices, Schmidt has said it’s possible that Siri could be a real and radical game-changer.

Schmidt may be right. And if he is, then Google will be facing a serious threat as Apple reinvents Google’s home turf of search.

With a “personality” that displays a unique understanding of humanity, Siri’s digital chromosomes enrich the user’s experience. This sets it apart from Google’s more mechanical offerings, and shows why Apple’s consumer-obsessed culture is so different from Google’s corporate DNA, which is as robotic and algorithmic as the “Android” name suggests.

There is rich irony here, as Apple disintermediates the greatest disintermediator of all time. When Google’s superior search service started, it practically single-handedly reduced the brand-driven experience that consumers had thereto relied on with directories and a fully editorialized Web. Google replaced those channels and home pages with 10 blue links. And in the process, became users’ destination of first resort 13 times per day.

And Apple has always been a curator extraordinaire – developing collections and exercising famous (and occasionally notorious) judgment to determine who deserves to be in its directories of songs and apps.

In all fairness, Page and his team are now trying hard to enrich the user experience by aligning their YouTube brand with media companies like Disney, and doling out big dollars for proprietary programming. The hope here is that YouTube can create dozens of lucrative user-friendly / user-favorite Web channels featuring comedians, sports stars, musicians and other entertainers. The company is building stocks of its ‘own’ media weapons in preparation for the coming war.

But, as always, it will be hard for Google to win the hearts of consumers when it comes to content; and it will be especially daunting because Apple is already so completely connected to users.

Meanwhile, with its enviable consumer connection, Apple will undoubtedly extract a toll from media companies, who still want to bathe in the warm digital light that emanates from the inviting and engaging brand Jobs built. And, as it has in every other media category, Apple stands to capture an outsize share of profits for delivering content into a magical consumer experience.

We all read the statistics every week documenting the meteoric new growth areas of the Internet, and they are impressive:

Online videois exploding, with annual user growth of more than 45 percent. Mobile-device time spent increased 28 percent last year – with average smart-phone time spent doubling. And social networks are now used by 90 percent of U.S. Internet users – for an average of more than four hours a month.

None of this is a newsflash. Every venture capitalist, Web publisher, and digital marketer is hyper-aware of these three trends.

But what’s happening to the rest of the Web?

The Web Is Shrinking. Really.

When you take these three growth areas out of the picture, the size of the hole left behind is staggering: the rest of the Web – the tried and true core that we thought would have limitless growth – is already shrinking.

Here are the facts:

When you exclude just Facebook from the rest of the Web, consumption in terms of minutes of use shrank by nearly nine percent between March 2010 and March 2011, according to data from comScore. And, even when you include Facebook usage, total non-mobile Internet consumption still droppedthree percent over the same period.

We’ve known that social is growing lightning fast – notably, Facebook consumption, which grew by 69 percent; but now it’s clear that Facebook is not growing in addition to the Web. Rather, it’s actually taking consumption awayfrom the publishers who compete on the rest of the Web.

And just what is the rest of the Web?

I have been calling it the “document Web,” based on how Google and other Web architectures view its pages as documents, linked together. But increasingly, it might as well be called the “searchable Web” since it’s accessed predominantly as a reference, and navigated primarily via search.

And it’s becoming less relevant.

In the last year, Facebook’s share of users’ time online grew from one out of every 13 minutes of use nationwide, to one out of every eight. In aggregate, that means the document Web was down more than half a billion hours of use (that’s more than 800 lifetimes) this March versus last March. And in financial terms, that represents a lost opportunity of $2.2 billion in advertising inventory that didn’t exist this year.

The Creation of a New, Connected Web

The change in the Web’s direction is a clear indication to me that we aren’t just in the midst of a boom for new interaction modes, but rather a generational overhaul of the Internet.

What replaces the declining searchable Web is a new and “fully connected” digital life. You may have heard this before. After all, the promise of the Web was to connect pages with hyperlinks. Well, this time, “connected” means much more. It means the Web connects us, as people, to each one of the individuals who’s online; and those connections, ultimately, extend from one of us to all of us.

Just as significantly, this all happens in real-time, and at nearly all times.

And here’s what’s different when you connect people, as opposed to pages: Now, the Web knows who we are (identity); is with us at all times wherever we go (mobile); threads our relationships with others (social); and delivers meaningful experiences beyond just text and graphics (video).

The connected, social Web is alive, moving, proactive, and personal; while the document Web is just an artifact – suited as a universal reference, but hardly a personal experience.

The Social Web Versus the Searchable Web

Analytical explanations – increasing smart-phone penetration, bandwidth availability, and technology sophistication – fill in some of the gaps as we try to understand this sea change, but they fall short.

Something larger is afoot, and it’s not about science or technology. Rather, as human beings, we have changed how we fit the Internet into our lives.

And the nature of the Web is changing to match. The old searchable Web is crashing; while the new connected, social Web is lifting off.

The implications for publishers are massive.

The last decade has been defined by the rise of Google as the nearly limitless supplier of traffic to digital media properties. And so a generation of digital media publishers developed and followed the same playbook: create lots of content around top keywords; engineer for search engine optimization (SEO); and expand the surface area in search engines to reach more users. The objective was to catch visitors in their net; expand reach – as measured by ComScore; look more impressive to advertisers; and capture more demand.

The landscape is changing, and fast.

SEO’s strategic value is quickly fading as Google’s growth slows and its prominence in distribution slides away. In its place, Facebook has become the wiring hub of the connected Web – a new “home base” alternative to Google’s dominance of the last decade. Facebook began receiving as many visits as Google in March 2010, and already garners more than three times as many minutes as Google each month from users, according to comScore. Looking ahead, the best projections of U.S. online reach indicate that Facebook will surpass Google on that metric in less than a year, too.

And with this change, the nature of the relationship between users and publishers is being altered fundamentally – and perhaps forever.

Search offers a utility relationship, connecting users to content for the briefest of transactions; typically, it provokes users to just one page-view so they can find a piece of information, and then they move on.

But social discovery builds a relationship. Leveraging social endorsements and an environment of serendipitous discovery, consumers meet publishers in a meaningful context. As a result, the relationship that forms is stronger – and, more importantly for publishers, it’s branded.

Unlike the ecosystem set up by Google, where the search engine ironically intermediates between users and the objects of their queries (so that users reinforce their loyalty to Google, far more than to the publisher), in the world of social publishing, the Facebook hub enables a direct, if constrained, relationship between users and media brands.

The results – at least for my own company, Wetpaint – are that social media brings more qualified eyeballs and retains them. People who come via social media stay longer on the first visit; and they are more likely to come back sooner and more frequently. Overall, our visitors from social networks have a relationship that’s several times stronger – and several times as valuable when measured in engagement, page-views, and revenues – than the relationships people form when then arrive through search.

The Human Connection

But it’s not just a change in mechanics. It’s a change in our human relationships.

But there’s even more, and this vast change foreshadows bigger and better impacts on our lives. The greatest innovators in social media are driving along exactly that edge today. As one friend commented recently on the full potential of connected lives, by being joined more closely together, we can increase empathy and meaning, while decreasing isolation.

Toward a Fully Connected Future

Admittedly, we’re early in the replacement cycle when it comes to the connected Web. Even for strong connected Web performers like Huffington Post, my own company, Wetpaint, and others, the sum total of traffic from Facebook, Twitter, video, and mobile may add up to only half the total, or less.

But the trend has tipped; and with that tip has come both the business necessity and the human impact potential of elevating the relationship.

As the document Web of old shrinks, the new connected Web expands and delivers experiences that make our time online more effective, efficient, and enjoyable.

And that changes the role of companies on the Web from mere content publishers or providers to truly connected digital partners for real people.
